Airbus is one of the world’s leading aircraft manufacturers, and it consistently captures approximately half or more of all orders for airliners with more than 100 seats. Airbus' mission is to provide the aircraft best suited to the market's needs and to support these aircraft with the highest quality of service. The Airbus product line comprises 12 aircraft models, from the 100-seat single-aisle A318 jetliner to the 555-seat A380 – which, as it has entered service in 2007, is now the world’s largest civil airliner.
